Qualitative screening test

Where can I go to get a complete qualitative screening test plan? BAIJIAN Materials Testing Agency provides qualitative screening test services. It is a national high-tech enterprise, a third-party materials laboratory, and a CMA qualification certification agency. It is a collectively owned scientific research institution with complete laboratory instruments and scientific research. The team is strong, adhering to the concept of scientific research and dedication, and is engaged in performance testing, non-standard testing, unknown substance detection and identification, industrial problem diagnosis and testing, composition testing, failure testing, corrosion testing, etc. Test reports will be issued in 7-15 working days, supporting 2D The code system checks the authenticity, and multiple laboratory branches across the country support door-to-door sampling/sample delivery testing services nationwide.

Test period: 7-15 working days

Test fee: Initial inspection of samples. After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment.

Qualitative screening test scope

Transistors, e-cigarette liquids, electronic and electrical products, dangerous goods, talc, polymers, hexabromocyclododecane, plastics for electrical appliances, environment Hazardous chemicals, automotive coatings, anti-fouling agents, etc.

Test project: Qualitative screening test

What is the role of the BAIJIAN test report? What can it help you solve? Questions?

1. Sales report. (Sales need to provide third-party testing reports to make their products more unique, let the product data speak for themselves, and make customers more confident in the quality of their products.)

2. Research and development reports. (In the process of developing new products, we encountered some thorny issues about ingredients. We used third-party testing data to find the cause of the problem, solve the problem in a timely manner, shorten the R&D cycle, and reduce R&D costs)

3. Improve products quality. (Discover problems with your own products through comparison of third-party testing data, improve product problems, improve quality, and reduce production costs)

4. Use of scientific research paper data.

What are the advantages of BAIJIAN Materials Testing Laboratory?

1. A collectively owned testing institution with complete qualifications and scientific, fair and accurate test reports.

2. Multiple laboratory branches are located across the country, supporting door-to-door sampling/sending samples for testing.

3. The testing cycle is short, the testing cost is low, and the experimental plan is more complete.

4. For initial inspection of samples, no testing fees will be charged during the initial inspection.

5. The test report supports scanning the QR code to check the authenticity.

BAIJIAN testing process

1. Send samples. (Communicate with engineers, submit your own testing requirements and send samples to our research institute)

2. Initial inspection samples. (After receiving the sample, conduct a preliminary inspection of the sample and formulate a detailed experimental plan)

3. Quotation. (After the initial inspection, a quotation will be made based on the customer's testing needs and the complexity of the experiment)

4. Both parties confirm, sign a confidentiality agreement, and start the experiment.

5. It takes 7-15 working days to complete the experiment.

6. Mail the test report and provide post-service.

The above is the relevant introduction to the qualitative screening test. If you have other needs, you can consult the laboratory engineer to help you solve it.
